Description

A kind of cam lifting body for automatic stereowarehouse track shuttle

Technical field

The utility model relates to a kind of cam lifting body for automatic stereowarehouse track shuttle, belongs to the logistics equipment technical field.

Background technology

Automatic stereowarehouse track shuttle claims again the RGV dolly, is the motor-driven rail mounted vehicle of a kind of use, is adapted at goods on the conveying tray of shelf bottoms.in tiered warehouse facility, goods turnover shelf are generally to transport in the tunnel between shelf by piler or fork truck, with portage to shelf, or carry from shelf, there is following shortcoming in the tiered warehouse facility of this form: use piler or fork truck that the tunnel need to be set in tiered warehouse facility, and the wall scroll shelf do not allow long at present, shelf are long, the tunnel also can be long, and the tunnel of walking has not only taken the actual use volume in warehouse, warehouse storage amount and degree of utilization have been reduced, and when using fork truck to pick and place goods, the shelf accident easily bumps, the access efficiency of goods is low.

In order to overcome above shortcoming, in the stereo storage rack warehousing system, adopt the use that matches with warehousing system neutral body shelf of RGV dolly, can effectively improve the space availability ratio in warehouse, the access efficiency of goods, the damage rate of reduction shelf, and simple to operate.Present RGV dolly is mainly to utilize eccentric shaft or cam with the shuttle jacking, to hold up pallet, goods is separated with shelf, and to fork truck picking position, car body descends and moves on to ready position the traveling gear of recycling shuttle with pallet carrying.Adopt eccentric shaft as the RGV dolly of lifting body, mainly make the rotation by eccentric shaft, drive the rotation of another driven shaft, this driven shaft can be eccentric shaft, can be also that the cam of installing on concentric shafts forms, realize the jacking support platform by the distance that does not wait from the axle center.Adopting the RGV dolly of cam lifting body, is mainly by the jacking axle directly being fixedly mounted cam, drive rotation by wheel chain, realizing jacking at present.

In above lifting body, adopt wheel chain to carry out powerdriven cam lifting body, because chain has tension variation, cause chain a tight state of end pine one end can occur, cause easily that in the jacking process, pause and transition in rhythm or melody, discontinuous defective mode appear in the jacking action; Adopt the lifting body of eccentric shaft, need to be with whole dolly jacking, need to the load weight of whole car body and pallet cargo of jacking motor, need to consume more multi-energy, thus because the increase of jacking power of motor has reduced again the service time of battery of RGV dolly, and this lifting body position of the fulcrum distance is little, and pallet holds up the poor stability that descends; And the whole overall height of the RGV dolly that adopts these two kinds of lifting bodies is higher, and the shelf guide rail cost that produces raises.

The utility model content

The technical problems to be solved in the utility model be to provide a kind of jacking good stability, cost for automatic stereowarehouse track shuttle low and can minimizing the lifting body of the energy that expends of equipment operation.

In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of cam lifting body for automatic stereowarehouse track shuttle, it is characterized in that: comprise two cam fixed bearings of being located at shuttle base two ends, lobe plate is located on the optical axis of cam fixed bearing; Two antifriction-bearing box bearings are located on the shuttle lamina tecti, and antifriction-bearing box is located on the optical axis of antifriction-bearing box bearing, and two antifriction-bearing box outside faces are tangent with the outside face of two lobe plates respectively; The two ends of cam pipe link connect respectively two lobe plates by optical axis, and push-rod electric machine is located on the car base, and push rod one end that can stretch connects push-rod electric machine, and the push rod other end connects the cam pipe link.

Preferably, described push-rod electric machine is formed a complete set of by motor and electric cylinder and forms.

The optical axis of telescopic band moving cam plate on the cam fixed bearing that a kind of cam lifting body for automatic stereowarehouse track shuttle that the utility model provides passes through push rod rotates, with antifriction-bearing box jacking or decline, finally realize the lifting of automatic stereowarehouse track shuttle lamina tecti.

The cam lifting body that the utility model provides has overcome the deficiencies in the prior art, adopts cam and regulations and parameters principle, and the jacking resistance is little and only need the weight of bearing body top board and pallet cargo, reduces energy consumption; Simple in structure, whole height can be controlled very low, has saved the guide rail cost, improves the shelf space degree of utilization; The Jacking point span is larger, has guaranteed the jacking stability of lifting body, and in the situation that guarantees that the jacking effect has reduced the spent energy of equipment operation, increases the period of service of battery.
